I'm creating a series of Data Driven Pages for parts of a railway. Different branches have different extents, names, scales, etc. For my project I will be using a uniform scale of 1:4000, and I've figured out how to get the dynamic text working to display the name of the current map. I also have them printing out with the timestamp and track name properly.
My one issue, however, is getting the layout to be dynamic. The tracks are sometimes vertical or horizontal so it's hard to put them in the layout view and get a good view of the horizontal boxes with a good scale since my layout is in portrait. I was wondering if it was possible to make it so that the orientation of the map view in layout can change when switching to a page that has a more horizontal section created from the data driven pages.
